Little Locals: Little Hands, Big Hearts

What if the smallest people in our community could make the biggest difference?

Children and families enjoying music and dancing together at a Little Locals community carnival in Celina Ohio — Big smiles. Little hearts. A community coming together for something bigger than itself.

Founded in 2026, Little Locals Community Impact Initiative was created to bring our community and its children closer together. It is about more than planning a fun day out. It is about helping children discover that they belong, that their voices matter, and that even the smallest act of kindness can change someone else's day.

Little Locals brings kids, families, neighbors, local businesses and community helpers together through experiences that build connections and teach kindness by doing. Because a child who learns to notice someone who needs a friend, lend a hand, or make someone smile is learning something that can last a lifetime.

You are NEVER too little to make a BIG difference.

Come be part of it. Bring your children, invite a neighbor, volunteer, or help us create the next moment a child remembers as the day they realized they could make a difference. Little Locals is for our kids, but the heart of it belongs to the whole community.
